IBO and German International School Doha are taking very seriously the rules of »Academic Honesty«, which implies that the students indicate clearly from which sources they take quotations that they include in their essays and oral performances.
The violation of this rules can lead to exclusion from final exams or failing the exams – depending on when and by whom the violation was discovered.
To get more details about this kindly read our own > GISD Academic Honesty Policy V.2.0 (st. 18.05.15).
With regard to the rules and practices for referencing, German International Doha is following the internationally recognised standard of APA:
